Best Claude Code Skills for SEO: The Seven Worth Installing

Most sites do not need fifty SEO tools. They need a small set of checks applied consistently at the right moments — before a launch, after a redesign, once a quarter. That is exactly the shape skills suit: folders of instructions an agent loads when a request matches, applied the same way every time instead of whatever you happen to remember the night before a deploy. A typical SEO skills folder holds seven entries. Here is what each one is genuinely for, in the order most people end up using them.

seo-audit: the orchestrator — install this one first

The honest description of this skill is that it runs technical, content, schema, backlink, local, and AI-search checks in one pass and merges the results into a prioritized report. That last part is what distinguishes it from the other six. Each specialist skill goes deep in one lane; seo-audit fans out across all of them and stitches the findings into a single ranked list. The hard part of an audit was never finding problems — it is deciding which of thirty findings to fix first. If you install exactly one skill from this folder, make it this one, and treat the other six as zoom lenses the orchestrator's report points you toward.

seo-technical-audit: the plumbing

Reach for this when rankings dropped mysteriously, when a redesign just shipped, or when a site was built fast and never checked. It covers crawlability, indexability, robots.txt and sitemaps, Core Web Vitals, JavaScript rendering, security headers, and which AI crawlers are allowed in. None of this is exciting, and all of it is a prerequisite — content and links cannot compensate for a site the crawler cannot read.

seo-content-eeat: the page-level quality pass

Once the plumbing is sound, this skill audits what the pages actually say. It runs Google's Who/How/Why test, flags thin content, checks whether articles are ready to be cited by AI systems, and cleans up the AI-typical phrasing that makes otherwise decent writing read generated. The right moment for it: after publishing a batch of posts, or when one section of the site was written by five different people to five different standards.

seo-schema: structured data without the guesswork

Schema is the classic task that is easy to half-do — a JSON-LD block copied from a tutorial, validated once, quietly broken after the third template change. This skill detects what structured data already exists, validates it, and generates Schema.org markup as JSON-LD, with templates for organization, product, FAQ, article, and local business types. Run it after template changes or when an audit flags missing structured data.

seo-backlinks: the off-site picture

Backlink analysis is where DIY efforts usually stall, because the premium data sources are expensive. This skill works with free sources to cover referring domains, anchor text distribution, toxic link detection, and the competitor link gap. That is enough to answer the questions that actually matter for a small site: whether the profile looks natural, whether a spammy directory run needs disavowing, and which links competitors hold that you do not.

seo-local: only if the business has a place on a map

Skip this entirely for purely online products. If the business serves a geographic area, it handles Google Business Profile optimization, NAP consistency, citation health, review signals, LocalBusiness schema, and multi-location edge cases. Most local visibility problems are hygiene problems, and hygiene is what skills are good at enforcing on a schedule.

seo-aeo-geo: the search layer that is still forming

The newest lane covers AI search optimization — showing up in AI Overviews, ChatGPT search, and Perplexity. It addresses citability, brand-mention strategy, AI crawler access, and platform-specific tuning, and includes a reality check on llms.txt, a young format tooling still overpromises on. Treat its outputs as informed hypotheses rather than settled best practice, and re-run it every few months as the platforms shift.

How to sequence the seven

A workable order: seo-audit first to get the merged report, then the specialist it flags as worst, then the rest as maintenance. If you are pre-launch rather than mid-flight, our SEO launch checklist for a small site pairs well with the first orchestrator run. The vibe-coded crowd can map the same findings onto our SEO checklist built for vibe-coded websites. The caveat that applies to all seven: a skill executes a checklist well, but it cannot invent a strategy you have not given it — the domain knowledge of what your buyers actually search for still has to come from you.

The meshcode angle

meshcode ships this SEO folder as installable skills inside a multi-pane agent workspace: open one pane for the seo-audit run, another to act on its top finding while the first still works, each pane an independent agent session with resumable context and visible diffs. Bring your existing Claude Code or Codex subscription, or use metered pay-as-you-go credits — the skills install the same way either route.
